Mandrake Linux Advisory: kdebase

Mandrake Linux Security Update Advisory

Problem Description:

A vulnerability was discovered in all versions of KDE 2.2.0 up
to and including 3.1.3. KDM does not check for successful
completion of the pam_setcred() call and in the case of error
conditions in the installed PAM modules, KDM may grant local root
access to any user with valid login credentials. It has been
reported to the KDE team that a certain configuration of the MIT
pam_krb5 module can result in a failing pam_setcred() call which
leaves the session alive and would provide root access to any
regular user. It is also possible that this vulnerability can
likewise be exploited with other PAM modules in a similar
manner.

Another vulnerability was discovered in kdm where the cookie
session generating algorithm was considered too weak to supply a
full 128 bits of entropy. This allowed unauthorized users to
brute-force the session cookie.

mdkkdm, a specialized version of kdm, is likewise vulnerable to
these problems and has been patched as well.
